Y A

'The' latter isi'prdvided with a b ref16 the'bobbin andfthere is also provided an' inclined guide which directs the incoming bobbin toward thefspring: Due to the fact that the shuttle may not always register/accurately with the transfer mechanism it is necessary to guide the incoming bobbin tofitscorrectjposition in I V V t g u H face '21 positioned toengage' an'Iincoming JbQbbin and direct' thefsarneso that the rings there- 7 0 ith the. notche s' *of-the Y "the. shuttle; When the weftyis' led through the charged at the biitt end 'it isj likely to lie across the inclined or cam -guifde,'and whenfthe ordif' nary form of bobbinisemployed. there is likelihood that the threadfwilt'be pinched or out. gon the guide. -It is an importantobject of my;

present invention .to provide; the bobbinwith a guide engaging surface which isnotched-so that H the thread can find its position in one of' the notches while the-guide, engages projections on,

It is a further vobject of my invention to pro vide two cooperating parts o'nefon the bobbin and one'on the shuttle adapted to effect proper. relative positionof the bobbin and shuttle, one. of said parts being so formed asjto permitthef placing ofthe weft out ofjreach of the other; part at the time of transfer.
